Subject: fscanf different behaviour


In investigating why f2c.exe is illbehaving under djgpp1.11 I found out
that fscanf behaves differently under 1.11. I don't know if this is
a bug in 1.11 fscanf or just a peculiarity in fscanf which depends on the
filemode or something, though not sure.

Look at the following small test example:
#include <stdio.h>
main()
{
   FILE *ip;
   int c;
   ip=fopen("test.dat","r");
   while(fscanf(ip,"%d",&c)!= EOF)
	printf("%d\n",c);
}
with test.dat containing
1
2
3
4
5
6

Under 1.10 the above program exited as expected when fscanf returned EOF.
Under 1.11 fscanf does not return EOF.

Any clues. I have not yet had time to look into the fscanf source and low
level stuff but will do so soon.
